Maybe someone's in the same pms boat❔🚣

A few days before or after my period depending I get an icky feeling after I pee. Like I feel uncomfortable as if I need a shower, although I don't. The feeling usually last no more than five minutes but has at times lasted up to 30minutes. This only happens the few days before or after my period. Anyone in the same boat or better yet know why? I've never been able to get an answer. (Ps it's not because of sanitary reasons, as it only happens at this specific time)
